Re: ~ Laser accessories you should own ~ **WTB durable diffraction gratings**
I've been unable to find any info on this on these forums or Google. If I missed a thread, I won't take it personally if you just post a link to that as a reply.
What I'd like to have is some sort of durable housing with diffraction grating(s) inside it. Ideally, I'd love to be able to stack and rotate the gratings, either across different housings or integrated into one housing that allows rotation of the gratings. Motorizing this rotation may also be of interest. This could be anything from a cap-style housing that would go over the emitting end of the pointer (this would be the easiest to use in a handheld situation, though I would be limited to one laser through it), to a small square or disc shaped device, to the pieces required to manufacture such a device.
If you haven't guessed, the idea is to be able to create a kaleidoscopic laser effect. I want it to be durable enough to survive in a pocket with keys in it, for example.
My pathetic, impulse home-grown attempt ended in failure as superglue wound up between two gratings.
If anyone has any thoughts on a device like this, or devices that would facilitate its construction, I'd love to hear them. It would have to be cheap
I didn't see this item on the list, so how about adding a simple SPECTROMETER to this list. With it, you'll be able to tell the exact wavelength that each of your lasers is generating.
I have one for sale right now in the B,S,&T Section of the Forum. It's simple to use, accurate to +/- 5nm's. Brand new condition, & I'm selling it for $30.00 with next day shipping.
It cost me $40.00 to buy new, & is still in NEW CONDITION .............. rob
